Total and Net Ionic Equations

Total Ionic Equation: When you write the dissociated form of the ionic compounds dissolved in water you have the total ionic equations.

Net Ionic Equation: During a double displacement reaction if one of the products formed is a compound with low solubility, which can be determined from the solubility rules; we say we have a precipitate. Writing the formation of the precipitate or the solid product formed from its constituent ions is called net ionic equations.Spectator Ions: The ions present in solution after a double displacement reaction, they do not precipitate. Hence they are called spectator ions. We strike through the spectator ions in the total ionic equation.

As a prelude start writing the dissociation products of the following ionic compounds and identify the compounds with low solubility.
